It has 381 installs sharing analytics, needs the vendor's cloud and was last updated October 23, 2026. Tech Controllers connects heating controllers from TECH Sterowniki to Home Assistant through the eModul web application. It talks to the vendor's cloud, so the controller must be reachable from the Internet and linked to an eModul account. Setup happens in the UI: sign in with the account username and password, then pick which controllers to import, with an option to put the hub name in entity names. Several controllers under one account can be imported individually. Zones appear as climate entities, alongside temperature, battery and humidity sensors and window sensors where available. The integration also provides sensors for eModul tiles, with names and translations taken from the eModul API, and it has limited support for menu handling. A repair notice can appear when a deprecated sensor is detected. Automatic summary of the README and code of mariusz-ostoja-swierczynski/tech-controllers.
